[PATCH] perf tests: Fix lib path detection for non-x86 architectures

[Suchit Karunakaran]

The existing Makefile logic for determining library paths was
hardcoded for x86 architectures, causing incorrect behavior
on other platforms. This patch implements a portable solution
using system bit detection.
